lie it known that l, lil/irritiert it. linien., :t citizen oit the United tito'tes, residing sit Detroit, in the county ot lll/"eyne end leitete of li/lichigon, here invented :i new und usetul Carburetor; of which the tollmving1 ti epecilicetion.

rlhis inifention relates to eerburetors. @no ot the objects is to provide simple and ellicient Valve mechanism 'liinder the con stent control. ot the operetor whereby the suppl),I oi 'luel in desired quantities to the cerfburetor mixing chamber is etliected.

With the toregoing end other objects in View, which will tippe/:ir es the description proceede, the invention consiste ot certein ferred 'forni oit the invention has been shown.

When the plate 28 is moved in the opposite direction the movement of the valve is reversed :successively and `the flow of fuel tothe branches 14C is cut off gradually.,` ThefplateuQ is connected to the throttle ivalve..9, :asy shownY at 36 so. that the valvesy will all; avork in proper relation, ythe. throttl'e valve gradually cutting `down thelflowsofwfuelwasfthe. rotary valves are eperatedlinthe manner described.

For..thewpurpose:ofwpriming the engine.y a groupoff passagesk is-extended tothe upped-portion of. thetconduit .4 or, in other words, to the conduit at a point near itsoutletyv'thesepasssages 4communicating with the passagelland being cont-rolled by a rotary valvefdwunder the-.controlof the operator. When the valve is opened fuel will be deliveredlin .separatesma-lljets so that it will be morel thoroughly mixed with the air than shouldthe s ameamountof fuel be delivered ina singlefjet.

By threadingfthe valves one within the otherthey aregiven a relativey longitudinal movement duringtheir relative rotation so thatthe passages throughthevalves are contracted gradually atl the time they are-being rotated outofregister with the passageslll.

What; is lclaimed is f- 1. In a earburetorfthe combination with separater-stationary fuel passages, of nested screw,l threaded" valves-in engagement with each other landpmounted for independentand simultaneous jrotation, Vsaid valves having passages therethroughnormally registering with-each other and With the fuel passages, and means for simultaneously and separately rotating the valves to impart. relativeannular and longitudinal movementlthereto to n'1ove,thepassage s in the valves gradual-ly into-orout of register with each other and with the2 corresponding Vstationary passages.

'Inaearbureton-the combination with separatestationary'fuel passages, of a tubularQvalve; ini-screw.V threaded engagement with the carburetor structure and provided with interior screw threads, there being a passage through said valve movable into and out of register with one of the stationary fuel passages, a screw threaded tubular valve within and engaging the interior threads of the first named vali/'0, there being normally registering passages extendmg through the two valves normally registering with ak second stationary fuel passage, said second valve being interiorly screw threaded, a screw threaded valve seated within and engaging the interior threads of the second valve, there being normally registering passages extending through all of the valves Aand normally registeriing-with a third stationary fuel passage, and means for-successively and simultaneously rotating the valves to gradually bring the passages therein into or out of register with each other and with the corresponding stationary passages.

3. ln a carburetor structure, the combination with separate stationary passages for discharging fuel, of an eXteriorly andv interiorly screw threaded valve in threaded engagement' with the structure and having a diametrical passage therethrough movable into register with one of the fuel passages, a tubular exterior-ly and interiorly screw threaded valve in threaded engagement with the first named valve, there being normally registering diametrical passages within the two valves movable into and out of register with a second fuel passage, and a third screw threaded valve within and in threaded engagement with the second tubular valve, there being diametrical passages within all of the valves normally alining with each other and with a third fuel passage, and means for actuating the valves to control the flow of fuel through the stationary passages.

In testimony that I claim the foregoing as my own, I have hereto ailixed my signature in the presence of two witnesses.
